The 2.4GHz band covers channels 1 through 14, with channels 1, 6, and 11 being the most commonly used as they don't overlap with each other. Choosing channels between these, specifically channels 3, 4, 8, or 9, could still result in interference due to overlap. Therefore, opting for either channel 1, 6, or 11, which are sufficiently spaced apart, will reduce the likelihood of interference. Channel 11 is often the last in the non-overlapping sequence and can be a suitable choice if the interfering equipment operates on lower channels.
